Police arrested four people this afternoon after they left handprints in red paint on the outside of a Northeast Portland military recruiting center.

Officer Cathe Kent, a Portland Police Bureau spokeswoman, said the four were among about 25 protesters against the war in Iraq.

Those arrested were identified as Sara Graham, 67; Bonnie Tinker, 59; Harry Kershner, 62; and Crystal Elinski, 35. Elinski refused a citation and was booked into the Multnomah County Detention Center, Kent said; the others were cited to appear in court on accusations of third-degree criminal mischief.

They apparently were members of the Seriously P.O.'d Grannies. A year ago on Good Friday, a half-dozen members of the group used red fingerpaint to leave handprints on a front window at the station, along with the number 3,627 -- the body count of U.S. service members killed in Iraq to that point.

The group arrived at the recruiting center about 11 a.m. to read the names of troops who have died in the past year, Tinker said. They hope the handprints will discourage people from joining the military, she said.

"We're using the bloody handprints because it's a sign to stop the war and bloodshed," Tinker said.

Last December, after a three-day trial in which the prosecutor likened them to terrorists, five "Grannies" -- actually, four women and a man, ages 56 to 76 -- were acquitted on misdemeanor criminal mischief charges.
